This is an emotional keys piece I composed back in 2010. It was originally done using the Sine Keys patch in FL Studio's Directwave. While I love that sound, I had some trouble getting it clear/loud enough. I recently redid it with a mix of FM and Suitcase electric pianos in Pro Tools, and I think it came out pretty well. I'll likely work on the sine keys version again soon, though, as that's my real vision for this song. It's deeper sounding, and you really FEEL the notes.

@hoboka: Thanks! Yeah, I think you're right about slowing it down. I do want to revisit this at some point to try to get the original Sine Keys sound from FL Studio sounding good, and when I do I may experiment with tempo.
